Initially I thought this multi tester was unreliable. Turns out I was the weak link. After reading other reviews and watching the product videos, I realized I wasn’t putting adequate pressure on the stone. After being mindful of the stone cleanliness, probe angle, and pressure, I’m identifying stones with precision. This is a prograde device which does require practice and patience. I’m extremely happy with the purchase.

El producyo aparenta muy buena calidad, pero no es lo que promete. Tengo casos en los que un diamante HPHT es leido como diamante cuando esta sobre la placa de aluminio suministrada y una vez montado en oro lo lee como Moissanita. Casos en los que pequeños diamantes naturales los lee como Moissanitas. Y casos en los que a las Moissanitas las lee como diamantes.. Aun limpiando, aun cambiando pilas, aun verificando angulo de toma, aun con todo lo que se recomienda hacer, lls errores de lectura son persistentes, por lo que no es confiable su uso. para eso, vale mas comprar un diamond selector de 150 pesos (conductividad termica) y un Moissanita terster de 150 pesos (conductividad electrica) y con menos del 10% de lo que vale este producto tienes los mismos o incluso mejores resultados de lectura, ya que con esos aparatos baratos si temgo lecturas persistentes de lo que se trata.
